I think he meant 'Kristen' not 'Christian (Serratos)' because he's talking about "Christian and Rob" being the 'seniors' to the newcomers' 'freshmen' status, and KStew and RPattz are the leads, so why would he mention Angela?

Also, he calls the Quileute tribe the "kill-i-wits," so I think he may just be nervous or didn't get the 411 on pronunciation.
